The GMRT 150 MHz all-sky radio survey - First alternative data release TGSS ADR1
We present the first full release of a survey of the 150 MHz radio sky, observed with the Giant Metrewave Radio Telescope (GMRT) between April 2010 and March 2012 as part of the TIFR GMRT Sky Survey…
Superluminal motion of a relativistic jet in the neutron-star merger GW170817
Radio observations using very long-baseline interferometry find that the compact radio source associated with GW170817 exhibits superluminal apparent motion between 75 days and 230 days after the merger event, which breaks the degeneracy between the choked- and successful-jet cocoon models.
The VLA-COSMOS 3 GHz Large Project: Continuum data and source catalog release
We present the VLA-COSMOS 3 GHz Large Project based on 384 hours of observations with the Karl G. Jansky Very Large Array (VLA) at 3 GHz (10 cm) toward the two square degree Cosmic Evolution Survey…
Illuminating gravitational waves: A concordant picture of photons from a neutron star merger
It is demonstrated that merging neutron stars are a long-sought production site forging heavy elements by r-process nucleosynthesis, which is dissimilar to classical short gamma-ray bursts with ultrarelativistic jets.
Birth of a relativistic outflow in the unusual γ-ray transient Swift J164449.3+573451
It is concluded that the tidal disruption of a star naturally explains the observed high-energy properties and radio luminosity and the inferred rate of such events, and the weaker beaming in the radio-frequency spectrum relative to γ-rays or X-rays suggests that radio searches may uncover similar events out to redshifts of z ≈ 6.

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced…
A radio counterpart to a neutron star merger
Radio observations constrain the energy and geometry of relativistic material ejected from a binary neutron star merger, and the detection of a counterpart radio source that appears 16 days after the event is reported, allowing us to diagnose the energetics and environment of the merger.
A mildly relativistic wide-angle outflow in the neutron-star merger event GW170817
The cocoon model explains the radio light curve of GW170817, as well as the γ-ray and X-ray emission (and possibly also the ultraviolet and optical emission), and is the model that is most consistent with the observational data.
A Multi-telescope Campaign on FRB 121102: Implications for the FRB Population
We present results of the coordinated observing campaign that made the first subarcsecond localization of a fast radio burst, FRB 121102. During this campaign, we made the first simultaneous…
A Strong Jet Signature in the Late-time Light Curve of GW170817
We present new 0.6–10 GHz observations of the binary neutron star merger GW170817 covering the period up to 300 days post-merger, taken with the upgraded Karl G. Jansky Very Large Array, the…
